"See this docker container? I wish I could run another one just like it, but I'll be damned if I'm going to type all those command-line switches manually!"
This is what
runlike does. You give it a docker container, it outputs the command line necessary to run another one just like it, along with all those pesky options (ports, links, volumes, ...). It's a real time saver for those that normally deploy their docker containers via some CM tool like Ansible/Chef and then find themselves needing to manually re-run some container.
Notice: This repo has been renamed. Used to be called
assaflavie/runlike. Sorry for the inconvenience.
This prints out what you need to run to get a similar container. You can do
$(runlike container-name) to simply execute its output in one step.
-p breaks the command line down to nice, pretty lines. For example:
$ runlike -p redis docker run \ --name=redis \ -e "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" \ -e "REDIS_VERSION=2.8.9" \ -e "REDIS_DOWNLOAD_URL=http://download.redis.io/releases/redis-2.8.9.tar.gz" \ -e "REDIS_DOWNLOAD_SHA1=003ccdc175816e0a751919cf508f1318e54aac1e" \ -p 0.0.0.0:6379:6379/tcp \ --detach=true \ myrepo/redis:7860c450dbee9878d5215595b390b9be8fa94c89 \ redis-server --slaveof 172.31.17.84 6379
Run without installing
runlike is packaged as a Docker image called assaflavie/runlike.
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \ assaflavie/runlike YOUR-CONTAINER
Or you can run it with alias, for example, save it in
alias runlike="docker run --rm -v /var/run/docker.sock:/var/run/docker.sock assaflavie/runlike"
Then you can run as local command directly
$ pip install runlike
This is very much a work in progress. Many
docker run options aren't yet supported, but the most commonly used ones are. Feel free to send pull requests if you add any or if you happen to fix any (of the many) bugs this package undoubtedly has.
Probably shouldn't use this in production yet. If you do, double check that it's actually running what you want it to run.
